It was permitted by Crown Petroleum Corp. and has since transferred to L.C.S. Production Company on the wellbore schedule.

Its 3 leases have reported 834K barrels of oil and 383K mcf of gas since January 1993, last reporting in July 2026. The leases carry 120 wells, so these are lease totals, not this well alone.
